I figured there would be some people here interested in this. You can get 4 free weeks of StarTiger for free, with no credit card required. You just have to sign up with a valid email address. It also works if you had a membership before that you let expire.

Go to StarTiger.com and hit "Join" and use this coupon code (copy and paste it as is) :

FREE-55B9-E723

Full disclosure - When somebody uses your coupon code, it gives you an entry into some contest drawings. You'll get one when you sign up, so feel free to post it in this thread in case any members want to use your referral instead of mine. I don't really care about the contest entries, I just wanted to share a great deal.
